During the Viking age, which mechanical consequence results following prolonged freezing temperatures impacting rope bridge materials?

💡 Explanation

Reduced wood and rope flexibility induces impacts because the embrittlement from freezing narrows material stress absorption capabilities. Therefore, bridges collapse with reduced loads, rather than remaining pliable under stress with the increased material strain offered at moderate temperatures.
